Potassium Hydroxide - KOH - Potassium, Oxygen and Hydrogen
All hydroxides contain two elements: oxygen and hydrogen. The hydroxide ion (OH⁻) consists of one oxygen atom and one hydrogen atom. Additionally, hydroxides typically combine with a metal or a cation to form a complete compound, such as sodium hydroxide (NaOH) or calcium hydroxide (Ca(OH)₂).

two hydroxides (OH-OH)
Disjoint means they have no elements in common. The union is the set of elements containing all elements from both sets. Since there is no overlap, the union will have 5+7 elements. Therefore the answer is 12.
The chemical formula for nitroglycerin is C₃H₅N₃O₉. A radical typically refers to a species that has one or more unpaired electrons and can involve a variety of elements depending on its specific structure. The number of elements contained in a radical can vary; for example, a simple radical like the hydroxyl radical (•OH) contains two elements (oxygen and hydrogen).

Group one elements (alkali metals) react with water to produce metal hydroxides and hydrogen gas. The metal hydroxides are basic in nature and the hydrogen gas is released as a byproduct of the reaction.
two hydroxides (OH-OH)
Scientist believe that stellar evolution contained only hydrogen and then helium.
If the unknown substance contained a mixture of two elements, it would exhibit properties that are a combination of those two elements. Its physical and chemical properties would be unique to the mixture, and further analysis would be needed to identify the specific elements present in the substance.
That would be the Atomic number. It tells you how many protons are contained in the nucleus of an atom. No two elements could share this number.
Disjoint means they have no elements in common. The union is the set of elements containing all elements from both sets. Since there is no overlap, the union will have 5+7 elements. Therefore the answer is 12.
The relation between sets refers to how two or more sets can be compared or connected based on their elements. Common types of relations include subset, where all elements of one set are contained within another, and intersection, which identifies shared elements between sets. Additionally, relations can involve operations like union (combining all elements) or Cartesian products (forming ordered pairs from elements of two sets). Understanding these relations helps in analyzing and organizing data in mathematics and various applications.
All 2A elements show the valency of two.
